Title: BUGFIX: Fix "Cancel Draft Changes" button.

I added the rollback action back into CMSMain so the rollback button has an effect - it just passes the call on to the CMSPageHistoryController.

Another fix was necessary, as the button's onclick wasn't calling ._super() so was firing the save action instead of the rollback action.
